The Blues has lost at Manchester City and lost to Blackburn in the Carling Cup and Ancelotti was disappointed at not beating Nicosia.
“The manager was really, really mad with the way we played in the second half,” explained Mikel.
“We had lost the last two games and, playing at home as well, we should have won the game.
“We played well in the first half but in the second half we didn’t move the ball quickly and you could smell the danger coming.
“It is good that we are now playing two games at home. We owe the manager because he is really mad and we have to make sure we win these next two games.
“It was a very big mistake from me, but the mistake is done now. I take responsibility for it but I think overall we didn’t play well enough in the second half.”
